Description
Summary:The current study explores the entropy and heat transmission properties of an MHD viscous hybrid nanofluid squeezed among two rotating parallel frames and saturated in a Darcy porous medium. This study is significant in technical and manufacturing procedures for heating and cooling. The modelling considers the two nanoparticles, zirconium dioxide Z r O 2 and cobalt Co suspended in base fluid ethylene glycol (EG). Additionally, it reflects the collective effects of magnetic field, heat source, buoyancy force and heat radiation. The basic governing equations related to the fluid model are transformed into dimensionless form. The numerical technique named bvp4c is used to solve the transformed dimensionless equations and plot the graphs for normal, axial and transverse velocities and temperature distributions. The important findings of notable parameters are examined concerning fluid distributions. The amalgamation of Zr O 2  +  Co\EG exhibits improved and embellished thermal properties. Furthermore, the Nusselt number and surface drag coefficient expressions are computed and examined. Previous research provides validation for this study. The findings exhibit that the squeezing number lowers the fluid temperature while raising the velocity components. The entropy production rate can be optimized by Eckert number and magnetic parameter.
